PROBLEM TO BE SOLVED: To provide a method of eliminating harmful animals and pest insects such as crows and cockroaches by laser beam.SOLUTION: Using automatic image detection technique by a computer from a camera image, harmful animals and pest insects as well as their vulnerable positions are detected. For example, it has only to detect a place in which haar cascade algorithm, SIFT, or a SURF feature vector matches most with the features of the vulnerable points. The position of the detected object is automatically irradiated with a laser beam. By the automatic control in the direction of the laser beam, the light spot of the laser beam in the camera image is controlled to coincide with the vulnerable point position of the object. The automatic control can use both an advanced method like intensive learning and a simplified method like a method of false position.COPYRIGHT: (C)2015,JPO&INPIT【課題】レーザー光線でカラスやゴキブリなどの害獣や害虫を追い払う方法の提供。【解決手段】カメラ画像からのコンピュータによる画像の自動検出技術で害獣や害虫とその弱点位置を検出する。例えばhaar cascadeアルゴリズムやSIFTやSURF特徴ベクトルが弱点の特徴と最もマッチする場所を検出すればよい。検出された対象の位置に自動的にレーザー光線を当てる。レーザー光線の方向の自動制御でカメラ画像中のレーザー光線の光点と対象の弱点位置が一致するよう制御する。自動制御は強化学習の様な高度な手法と挟み撃ち法(Method of False Position)などの簡単な方法のどちらも使える。【選択図】図1
